I'm 25 years old, and my last period was (july 30) . I got some brown discharge on 24th August then stopped and today also got few drops of brownish discharge, I have not yet noticed blood! What is wrong with me? I'm virgin. I'm taking iron tablets prescribed by the doctor for 2 months ,last month I got my regular period,but this month happening like this... Please I need real advice!

Im really scared and I need an answer!

****now I'm wearing a pad just in case, but all there is the brown discharge, also if it is only spotting how long will it last?
Also is it normal for there to be brown discharge on the pad instead of my period?
